' .To all whom it 'mu/y comer rt:

'Be it known that 'I," Fnmnmon- WILHELM KLEVER, vmanufactu'rer, a subject of the Iierman Emperor, residing at: 6: Branden burgerstrasse, Cologne-on-the-Rhine, v Germany, have inventedcerta'in newand useful Improvements in and Relating to the Manufacture of Lubricating and Anticorrosive Oils; and I do herebydeclare the following- 10 to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 1

This invention relates to the manufacture of lubricating and anti'corrosi've oils, cape cially of such oils, which are ada ted to solve or to remove the residues 0 nitric gunpowders from the bore offire'arms.

The invention consists 1n mixing alkali 2 0 oleates with hydrocarbons and alcohol or alcohols which have a high boiling point. Processes are known for renderlng hydrocarbons, paraflin oils, mineral oils or 'vaseline oils, capable of =forming' emulsions, which processes consist in adding alkali oleates to the said hydrocarbons or the like which are insoluble in water when employedalone. The less alkali oleates areadded to the hydrocarbons and the like, the more the lubricating and anticorrosive qualities of the mixture obtained are increased. The' usefulness of the said oils was hitherto impaired by the fact j that the storage of such oils as well as variations of temperature some 5 times caused separation of the oils and the alkali oleates, the density of the several components not'being the same, and thereby those qualities by which theyv are rendered capable of form' emulsions were; de-

4 stroyed. This draw ack is obviated by my invention which will'be'. fully described in the following'specification.

In carrying out my process, 1* first add to I the alkaliolea'tes, beforemixing them with y H able of formin an emulsiornfan alcohol or acohols havin a h 1 boiling point and whichQcan be heate to'tie' boilin point without, v..dec(imposition. I have ound that glycerin, which is sometimes considered to be an' alcohol', and ethyl alcohol cannot-be satisfactorily employed'in carrying out my recess but' I can use'of the aliphatic series'a mono acid.

so be employed.

Preferably-I em loy pinacone, omanthylor hepty -alcoho, 'caprylor octy'laloohol and buty'lalcohol. Or, I mix the h drocar'bonsand the like with the alkali o eates and then add the said alcohol or alcohols to the resulting mixture." By the admixture of high boilin alcohols the quantityof alkali oleates adde to the'minera'l oil ma be reduced to such extent that the alkah oleates together with the-alcohol, amount to about 15% of the mineral oil. Furthermore the newcompounds obtained are capable of dissolving or removing the destructive residues which remain in the bores of firearms when fired with nitric powders. The lubricants composed according to myinvention combine with the said residues, which in conseuence are removed more speedil and t oroughly1 than it was hitherto possible by mere mec anical action by means of'other The arms are therefore preserved in a more erfect state than formerly.

The 'gh-boiling alcohols above referred to do not combine with the alkalies themselves; nevertheless the combination which is necessary for the present purpose can be effected forinstance by first'combinin the oleic acid with the alkalies and then a ding the high-boiling alcohol, or by first embodying the latter into the oleic acid, then adding the alkalies and finally incorporating the resultin mixture with the hydrocarbons and the li e, thus, producing. the'desired qualities. The roportion of high-boiling alcohols and al ali oleates'varies from 15 to 30 per cent., accordin to the quality, density or viscosity of the hy rocarbon to be improved.

If the hydrocarbon which is to be employed contains alcohol which would be decomposed when subjected to a high temperature, such alcohol may be removed and replaced wholly or to any desired extent b alcohol of the proper character. If 0 y a transito efiect istobe reduced the high boiling a cohol may be ad ed to the finished. product preferably under pressure of from about 1 kg. per sq. cm. to 4 k per sq. 'cm.

and to an amount of not excee in 4%.

As the proportion of mineral o' .and mixture of high boiling alcohol and alkali oleates required to obtain the desired results will vary or depend upon the particular oil employed, it is necessary to determine such pro ortions by experiments. with solutions coo ed to a 'tem erature of from minus 10 to 20 C.
